Read the full statement (115 words)
When intended to promote fusion of the cervical spine (CI-C7) in skeletally mature patients, the Sure Lok Mini Posterior Cervical/Upper Thoracic System is indicated for the following:
-DDD (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiologic studies)
-Spondylolisthesis
-Spinal Stenosis
-Fracture/dislocation
-Revision of previous cervical spine surgery
-Tumors
The use of polyaxial screws is limited to placement in the upper thoracic spine (T1-T3) for the purposes of anchoring the construct. Polyaxial screws are not intended to be placed in the cervical spine.
The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical (C1-C7) spine.
